Carl's answer is correct: you are not required to file a tax return, based on the information you provided, regardless of whether you are someone else's dependent or not.
But, for others reading this, some clarification may be needed. The $12,200 standard deduction and filing requirement applies only to people who cannot be claimed as a dependent.
The filing requirement for people who can be a dependent is:
- Total income (wages, salaries, taxable scholarship* etc.) of more than $12,200.
- Unearned income (interest, dividends, capital gains) of more than $1100.
- Unearned income over $350 and gross income of more than $1100
- Household employee income (e.g. baby sitting, lawn mowing) over $2100 ($12.200 if under age 18)
- Other self employment income over $400, including box 7 of a 1099-MISC
- Gross income was at least $5 and his spouse files a separate return and itemizes deductions
*Taxable scholarship, including Pell grants, is treated as earned income, but only for purposes of calculating a dependent's standard deduction.
